I think the collectors showed that they want a lower quantity mint of the $200 strikes. Almost 100 went out in less than 5 days.
I believe that it is a win situation for collectors, sellers and the casinos.
My guess is that the Palms will issue more than 150 of the Seattle Slew strikes.
If they issue 150 they sell so fast the casinos probably wished they had issued 250 and if they issue 250 they sell so slow the casinos probably wish they only issued 150.
